The days of driving a car around Central Park will likely come to an end next year when a new administration takes over City Hall.

All four Democratic mayoral contenders have said they’d like to banish cars from the three-lane roadway that rings the park, leaving it exclusively for bikers, in-line skaters, runners and pedestrians.

Three of the candidates have backed a three-month trial so the Department of Transportation can gauge the impact on surrounding streets.

Public Advocate Mark Green, who backs a car-free park, said he’d want to start first with a study of traffic impact before closing the road.

“A park should be a park, not a highway,” said Green spokesman Joe DePlasco. Still, he said the city should determine the impact on neighboring streets before closing the road.

The question was posed to the candidates by the Sierra Club, based on a proposal by transit and environmental watchdog groups, including Transportation Alternatives.

The traffic ban would affect only the road around the park, not the transverse roads that run east and west.

“This is politically seismic because, in at least the last two mayoral elections, the candidates wouldn’t even talk about banning cars from the park,” said John Kaehny of Transportation Alternatives.

Automobiles are now barred from the East and West drives on weekends and from 10 a.m. to 3 p.m. and 7 to 10 p.m. weekdays.
